5D mkii w/vaf-5d2 vs 5D mkiii?
 

As far as image quality goes, would the mkiii blow the 5d mkii w/vaf-5d2 out of the water? Or would the difference be negligible? From what I have read about the vaf-5d2, you can increase the in camera sharpness some bringing back some of the detail you lose when it is all the way down.

Also, do we have any idea if magic lantern would be able to work on the mkiii? Or, is this one of those things we will just have to wait and see when it finally gets released?
